Compare any two graphics cards:
GeForce GTX 580 3GB vs Radeon RX 5500 XT
IntroThe GeForce GTX 580 3GB makes use of a 40 nm design. nVidia has set the core speed at 772 MHz. The GDDR5 RAM works at a frequency of 1002 MHz on this model. It features 512 SPUs as well as 64 TAUs and 48 ROPs.
Compare that to the Radeon RX 5500 XT, which comes with a clock frequency of 1717 MHz and a GDDR6 memory frequency of 1750 MHz. It also uses a 128-bit bus, and uses a 7 nm design. It is comprised of 1408 SPUs, 88 Texture Address Units, and 32 ROPs.
Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The Radeon RX 5500 XT should theoretically perform just a bit faster than the GeForce GTX 580 3GB in general. (explain)
Texel RateThe Radeon RX 5500 XT is a lot (approximately 206%) better at AF than the GeForce GTX 580 3GB. (explain)
Pixel RateThe Radeon RX 5500 XT should be much (more or less 48%) faster with regards to anti-aliasing than the GeForce GTX 580 3GB, and should be able to handle higher screen resolutions without slowing down too much. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
